Definition
Land cover types and global spatial patterns for QCE Geography Unit 3
Define Land cover
Land cover is the observed biophysical cover on the Earth's surface, such as forest, grassland, water or built-up area. Land use is the social and economic purpose for which people use that land.
Key fact
Demographic transition and population structure for QCE Geography Unit 4
Tell me about Birth rates, death rates and natural increase
The model is driven by two rates. The crude birth rate is births per thousand people per year; the crude death rate is deaths per thousand per year.
Key fact
Biodiversity and ecosystem impacts of land cover change for QCE Geography Unit 3
Tell me about Biodiversity and ecosystem services
Biodiversity operates at three levels: genetic diversity (variation within a species), species diversity (the number and balance of species), and ecosystem diversity (the variety of habitats).
Key fact
Managing challenges in a megacity for QCE Geography Unit 4
Tell me about Choosing a challenge and a place
The task narrows to one megacity and one challenge so you can go deep. Pick a challenge with clear causes, clear impacts and known management responses, for example Jakarta's flooding and subsidence, Lagos's transport and housing, Delhi's air quality, or Dhaka's flood vulnerability.
Key fact
The carbon cycle and land cover for QCE Geography Unit 3
Tell me about Photosynthesis, respiration and sequestration
Plants draw carbon dioxide from the atmosphere through photosynthesis and lock the carbon into leaves, wood, roots and, over time, soil organic matter. This removal is called sequestration.
Key fact
Managing local population change in Australia for QCE Geography Unit 4
Tell me about Reading demographic characteristics
A population pyramid is the central tool. A wide base means many children (a young, growing population); a top-heavy pyramid means ageing; a bulge in the working ages with a narrow base suggests in-migration of workers and few families.
Key fact
Land cover change and climate change for QCE Geography Unit 3
Tell me about Mechanism 1: carbon
Forests, grasslands, soils, wetlands and peatlands are carbon stores. Living vegetation absorbs carbon dioxide through photosynthesis (a carbon sink).
Key fact
Megacity distribution and world cities for QCE Geography Unit 4
Tell me about Defining megacities and world cities
A megacity is a size category: an urban agglomeration usually defined as having more than 10 million inhabitants. The count of megacities has grown rapidly, from a handful in 1970 to more than thirty today, and is projected to keep rising.
Key fact
Climate feedback loops and land cover for QCE Geography Unit 3
Tell me about Positive feedback: the ice-albedo loop
The ice-albedo feedback is the clearest example. Bright snow and ice reflect most incoming solar energy (high albedo).
Key fact
Megacity growth and urbanisation challenges for QCE Geography Unit 4
Tell me about Megacities and urbanisation
In 1950 only a couple of cities exceeded 10 million; by the 2020s there were more than thirty megacities, most in Asia and Africa. Urbanisation is the increasing share of people living in urban areas, distinct from urban growth (the absolute rise in city population).
